How to Bore Sight a Rifle for Optimal Accuracy

If you’re a hunter, you know the importance of having an accurate rifle. Even a tiny miscalibration can mean the difference between hitting your target and missing completely.

If you’re looking to improve your accuracy when shooting, then learning how to bore sight a rifler is a great place to start. Bore sighting is the process of aligning the barrel of your gun with the sights on the gun.

Bore sighting a rifle is an important process in ensuring optimal accuracy. In this blog post, we will teach you how to bore sight a rifle for optimal accuracy. We will also provide some tips on how to make sure that the process goes as smoothly as possible. Let’s get into it.

What Is Bore Sighting?

Bore sighting is the process of aligning the sights of a firearm with the bore of the weapon. This is typically done before zeroing the weapon, in order to save time and ammunition. Bore sighting is a useful technique for setting up a new scope or for checking the accuracy of a rifle that has been moved or stored for an extended period of time. While bore sighting will not guarantee that a rifle is perfectly accurate, it can help to ensure that it is close.

Bore Sighting Safety Tips

When discharging firearms, it is always important to take safety precautions. This is especially true when bore sighting, as there is a risk of harming both yourself and those around you. To help avoid accidents, it is important to follow some basic safety rules.

First, make sure that the firearm is unloaded before proceeding. Next, ensure that the barrel is free of obstructions. Finally, make sure that the target is in a safe location – for example, down range at a firing range. By following these simple steps, you can stay safe while bore sighting.

How to Bore Sight a Rifle Using a Device

There are many different ways to approach the bore sighting process, but one of the simplest and most effective methods is to use a bore sighting device.

Laser Bore Sighter

One relatively simple method is to use a laser bore sighter. This device projects a beam of light from the barrel of the rifle, allowing the shooter to see where the bullet will strike at various distances. Bore sighters are available in a variety of different models, but the basic process is generally the same. To bore sight a rifle using a laser bore sighter, follow these steps:

  1. Remove the bolt from the rifle and look through the barrel to identify the point where the laser beam intersects with the bore. This is the point where the bullet will strike at close range.
  2. Adjust the elevation knob on the scope until the crosshairs are aligned with this point.
  3. Rotate the windage knob until the crosshairs are centered on the bore.
  4. Replace the bolt and load a round into the chamber.
  5. Aim at a 25-yard target and fire a shot.
  6. Adjust the scope as needed based on where the shot actually strikes. 
  7. Repeat steps 5 and 6 until the shots are consistently hitting the 25-yard target.

After following these steps, you should be able to hit your target with greater accuracy.


One of the most reliable ways to bore sight a rifle is using a collimator which works similarly to a laser bore sighter. The collimator device projects a beam of light into the bore of the rifle, allowing you to line up the sights with the center of the beam. Here’s how to bore sight a rifle using a collimator:

  1. Attach the collimator to the muzzle of the rifle. Make sure that it is securely attached and that there is no movement between the device and the muzzle.
  2. Look through the scope or sights of the rifle and find the beam of light projected by the collimator. 
  3. Center the crosshairs or front sight on this beam.
  4. Once the sights are lined up with the center of the beam, adjust the windage and elevation screws on the scope or sights until they are in their correct positions.
  5. Remove the collimator from the muzzle and take your rifle to the range to test-fire it.
  6. Make any necessary adjustments until the rifle is shooting where you want it to.

By following these steps, you can bore sight your firearm quickly and easily, ensuring that your shots are on target.

How to Bore Sight a Rifle Without a Device

There are a few different ways to bore sight a rifle, but the most common method is to use a laser bore sight device. Fortunately, there are alternate methods you can try if you don’t have one. With a little patience, you can bore sight your rifle without any special equipment. 

Identify the Mechanical Center

The first step is to identify the middle of the scope’s mechanical adjustment range. This is usually done by finding the point at which the windage and elevation turrets are centered. Once this point has been identified, the next step is to find a target at a distance of 25 yards or more.

The target should be placed in the center of the field of view, and the rifle should be fired at it using a safe backstop. The point of impact should then be adjusted so that it is in line with the point of aim. Finally, the rifle should be fired at a second target to confirm that the alignment is correct.

By following these steps, it is possible to bore sight a rifle without the use of any special tools.

Look Through the Scope

The “look through the scope” method is one of the easiest ways to bore sight a rifle. However, this method is not the most precise one. Here is how to do it:

  1. Make sure the rifle is unloaded and pointed in a safe direction. 
  2. Remove the bolt or action and look through the barrel from the breech end. 
  3. Align the barrel with a distant object, such as a door knob or piece of furniture. 
  4. Once the barrel is lined up, replace the action and tighten it down.
  5. Take a look through the scope and adjust the windage and elevation knobs until the crosshairs are aligned with the object in the barrel.

Bore sighting with this method should get you close to your target, saving you time and ammunition when you head to the range.


What is the purpose of bore sighting?

The purpose of bore sighting is to align the rifle’s barrel and sights so that they are in the same line of sight. This is important because when the sights are not properly aligned, the bullet will not hit the target.

What distance do you bore sight a rifle?

Bore sighting can be done at any distance, but it is typically done at 25 yards. This will help to ensure that your shots are accurate when you’re hunting.

How accurate is bore sighting a rifle?

Bore sighting a rifle is an accurate way to adjust your sights so that your shots are more likely to hit their target. However, it is not 100% accurate, and there is always the chance that you will need to make further adjustments once you are actually hunting. Even so, bore sighting is a quick and easy process that can help improve your accuracy and give you the confidence you need when you’re out in the field.

Is a bore sight worth it?

Some shooters feel that bore sighting is essential for getting accurate shots, while others believe that it is not 100% accurate and that further adjustments are often necessary. Ultimately, it is up to the individual shooter to decide whether or not a bore sight is worth it for them.

What is a bore sight kit?

A bore sight kit is a tool that helps you accurately bore sight your rifle. It typically includes a collimator, which is a device that projects a beam of light into the barrel of the gun, and a sighting target, which allows you to center the crosshairs or front sight on the beam of light.

Final Thoughts

Bore sighting is the process of aligning the sights of a firearm with the barrel. There are several different methods of bore sighting, but the most common is to use a laser bore sighter. You can learn how to bore sight a rifle by yourself with a few simple tools, or you can take your rifle to a gunsmith or shooting range and have them do it for you.

Bore sighting a rifle is a simple and effective way to improve your accuracy. However, it is important to note that bore sighting should only be used as a starting point, as there may still be some minor adjustments that need to be made at the range. But by taking the time to do this, you can be more confident that your shots will be on target. Give it a try next time you’re at the range.
